------------------------------
Summary: Expose scanNext stats to region server level
Key: HBASE-13369
URL: https://issues.apache.org/jira/browse/HBASE-13369
Project: HBase
Issue Type: Improvement
Reporter: Ted Yu
Assignee: Ted Yu
Regions have a scanNext_num_ops stat but there is no such stat at the
regionserver level. The num_ops metrics at the RS level (exposed through JMX)
are as follows:
{code}
"SyncTime_num_ops" : 54,
"AppendSize_num_ops" : 56,
"AppendTime_num_ops" : 56,
"Append_num_ops" : 0,
"Delete_num_ops" : 0,
"Mutate_num_ops" : 0,
"Get_num_ops" : 0,
"Replay_num_ops" : 0,
"Increment_num_ops" : 0,
"QueueCallTime_num_ops" : 53,
"ProcessCallTime_num_ops" : 53,
{code}
We need a scanNext_num_ops, along with 95th percentile stat, at the RS level.
